Abstract: Abstract The  specification  describes  thermal  ink  jet  (TIJ) processes  and device structures produced thereby wherein  either heater   resistors  or  heater  resistor-diode  combinations  are constructed vertically upward from a common supporting substrate.          A lower or first metal level conductor pattern provides one  part of  an  X-Y  matrix multiplex connection  to  the  resistor/diode components,  and  a second,  upper metal level conductor  pattern forms the second part of the X-Y matrix multiplex connection.  In this manner,  the multiplex drive circuitry for the TIJ printhead resistors/diodes   may be fabricated (integrated) directly on the thin film resistor (TFR) printhead substrate.   Additionally, the second level metal conductors which overlie the resistive  heater and  diode  elements  also  serve  as a barrier  shield  to  ink corrosion and cavitation wear.

Granted: 1992-06-09
Abstract: ABSTRACT OF THE DISCLOSURE           A seeding machine has a drum and roller urged together to define a seed trough.  Bristles close one end of the trough and a hopper adjacent that end feeds a continuous supply of seeds to the trough.  The seeds flow along the length of the trough and are discharged at the opposite end of the trough which is open.  A funnel collects the discharged seeds and returns them to the hopper. The drum is provided with a series of axially extending rows of holes which are coupled to a vacuum source as each row passes through the tumbling seeds in the trough.  A single seed is attracted to each hole and is carried by the drum to a discharge location where the hole in question is disconnected from the vacuum source and instead connected to a source of pressure which then acts to eject the seed from the drum.

Abstract: ABSTRACT            A turbidity meter has a sensor unit supported in a fluid under test with a light source and at least two light sensors supported so that one light sensor is in line with the source to receive transmitted light and the remaining sensor or sensors are arranged to receive light scattered by  the  fluid.    Both the source and the  sensors have diffusers connected to a source of pressurized fluid so that a thin layer of this fluid is caused to flow over lenses of the source and sensors to prevent deposition of material from the fluid under test.  The signals from the sensors are digitized, and the intensity of the source is digitally controlled to maintain at least one of sensor signals within a suitable range, thus enabling operation over a wide range of turbidities, and automatic selection of turbidimetric and nephelometric modes of operation as appropriate.

Abstract: ABSTRACT This invention relates to a pyramid polygon scanner wherein the differential scan length between multiple beams can be eliminated by tilting thebeams with respect to the photoreceptor surface. Then the beam with the shorter scan lengths when the beams are normal to the photoreceptor, travel a greater distance before they impinge on the photoreceptor. At the start or end of scan the scan angle is not zero, so the scan lengths for the beams with the larger traveldistances are increased by the extra distance multiplied by the tangent of the scan angle. At the proper tilt angle, all scan lengths at the photoreceptor are the same. Since the angular scan rate of all the beams are always the same, over the entire scan, the scan lengths of the individual beams will always be the same, at any fraction of the total scan. Thus the information written onto the photoreceptor by the multiple beams will be in alignment for all simultaneous beams.
